My invention relates to holders and oonnections for fluid gages' being more `espe-- callfy' intended for use in locomotives.

One-objeetof my invention is to provide'- in fplace uponthe gage holder and making' the eonneotionwith the Huid pipe, the two results .being accomplished by the' operation oi asingle lever. l 'A 'other object is to 4regulatingg the tension of the springrwliieh maintains the fluid connection. n. Otherfohjeetsivvillappear hereinaftenas proceed with the description of that embodiment of the invention, which, for-the purpose of the present application is illustrated in the accompanying drawings in which:

Figure 1 is a front elevation of the gage holder withthe gage in place thereon. Fig, 2 is a similar view with the gage removed. Fig. 3 is a front elevational vie-W of a double gage holder with gages in place thereon.

whereby aiiniiigpassages zsndaeare stp-Tg5 plied through which fthe" l'ld' n In Fig. il have illustrated a slight modication in the pipe connection whereby I am' enabled to coin ensate for any adjustment in the tension oi the spring hy means of the nuts 16 and 17 that may be necessary. To this end I provide the gage with a' depending srew-threadedpipe 30 upon which is threaded a sleeve or nut 31 havin socket and perforation similar to those o the pipe connection 25. Rotation .of sleeve or nutl 31 to the riglitor left will, of course, cause it to move up rardly or downwardly, respectively.

ln F'ig. BI hav illustrated the application being precisely similar to t yin the pipes 34 andv- 35, respectively. The mechanism `for shifting the ipes 34 and 35, t for shiftingv the pipe 13, further description will be unnecessary.

From the foregoing, the operation of my improved age holder and pipe connector will be obvious. When it is desired toput a gage in place, the handle 20 or (as in the case of the connetion shown in Fig. 3) the handles 20 are rotated, causing the cam surfaces 15 and 19 to ride upon each other until their highest points are in contact whereby the pipe 13 or pi es 13, 34, and 35, as the Acase may be,'are ulled downwardly against the action of the spring or springs 22. The gage will then be placed in position with its back rim 8 in the grooves 7 of the fingers 6 and its lower .pipe connection or connections will be caused to ride over the rounded head or heads 24 of the Huid pipe or pipes. The gage being in place, the sleeve or sleeves 18 are permitted to rotate into their normal positions as illustrated in Figs. '1, 3 and 5, whereupon the gage is locked in place and the pipe connections made tight by the pressure of the springs 22. In removin a gage the reverse of these operations is; gollowed. y

I claim as my invention: ,Q

1. The combination with a gage holder comprising a frame having forwardlyj' a gage and an oppositely located ball headed pipe sprin pressed toward said iingersg'of a gage, an a pipe connection extendingohtwardly from one side of said gage, said pipe connection having a socket in its outer extremity adapted to being engaged by the ball headed pipe. j

x, tending fingers adapted to engage the rimeff' 2. In combination, a gage, an outwardly extending pipe connection thereupon, a gage holder, a, pipe longitudinally slidable therein, the adjacent extremities of said pipe con- A nection and ,fpipe being adapted t0 engage and form a tight joint, resilient means acting upon said pipe to maintain said joint, means upon the gage holder opposite the pipe for engaging said gage and means for retracting said pipe against the action of the resilient means.

3. In combination, a gage holder, a pipe mounted thereon to be capable of slight longitudinal reciprocat-ion, a gage having an outwardly extending screw-threaded pipe provided with a `Socket at its outer extremity to receive the adjacent end of said reciprocable pipe, and resilient means ating on said reciprocable pipe to hold it in engagement with said socket, the socket extremity of the pipe connected with the gage, being adjustable to regulate the tension of said resilient means. i

4. In combination, a gage holder, a mounted thereupon to be capable of slight longitudinal reciprocation, a gage having a pipe connection adapted to register with said plpe in one position, resilient means for ma1ntaining the pipe in the latter position, la cam mounted upon said pipe, ,a cam mounted lupon said gage holder in a position to be engaged by the first named cam and means whereby said Yfirst named cain may be ad justed longitudinally of the ipe.
